针对多指标多标度大群体决策问题,提出一种基于随机占优准则的决策方法。将参与决策人针对各指标给出的方案评价信息转化为关于指标评价标度的概率分布,然后依据随机占优准则判断并确定两两方案之间比较所具有的随机占优关系,并构建相应的随机占优关系矩阵。在此基础上,运用PROMETHEE Ⅱ方法得到方案的排序结果。实例分析表明,所提出的方法具有可行性和有效性。     

不同极性吸附质交替吸附对吸附性能的影响

研究四种吸附剂(两种市售活性炭和两种自制硅胶)对甲醇、正己烷和水蒸气的交替吸附性能以及动态吸附过程中吸附剂温度的的变化。结果表明:吸附顺序的不同对吸附剂最后总的吸附量没有较大的影响,相比先吸附正己烷对吸附剂的影响大于先吸附甲醇对吸附剂的影响;活性炭吸附少量的甲醇对水的吸附率影响较大,AC-1吸水率降低71.7%,AC-2降低98.4%;硅胶吸附少量的甲醇后再吸附水时吸附率为负,而先吸附少量的水后因为甲醇和水的互溶,所以硅胶吸附甲醇的效果会得到一定的提高,SG-1提高69.5%,SG-2提高了81.1%,因此在需要紧急处理时可以先短暂的吸附水之后再去吸附甲醇;甲醇的解吸率高于正己烷的解吸率,硅胶的解吸比活性炭的解吸的更彻底,解吸之后活性炭的吸附率明显降低,因此连续性长期使用可以选择硅胶作为吸附剂;AC、SG最大温差分别为23.3℃、13.5℃、18.2℃和21.4℃,AC-2对甲醇具有较大的吸附量,温度变化较小,为以后应用于醇类的吸附回收技术提供实验支撑。     

猪SOCS7基因克隆、组织表达图谱分析及剪接变体鉴定

以家猪肌肉来源 cDNA为模板,克隆了 SOCS7的编码区 cDNA 全长并发现了三种剪接变体(命名为：SOCS7-v1、SOCS7-v2和 SOCS7-v3).家猪 SOCS7编码区 cDNA 全长为1785bp,由9个外显子组成,编码含581个氨基酸残基的蛋白质.家猪SOCS7基因的三种剪接变体分别编码含547、520、512个氨基酸残基的蛋白质.通过RT-PCR方法,本研究对家猪SOCS7基因及其剪接变体的组织表达图谱进行了分析,结果显示：SOCS7在精巢、小脑、背肌、腹肌、股肌、大脑、下丘脑、心脏、肝脏、脾脏、小肠等组织中均有表达,在精巢中表达信号最强.SOCS7-v1和 SOCS7-v2除大脑外的19个检测组织中均能检测到较强的表达信号, SOCS7-v3在除精巢外的19个组织中均有表达.以上实验结果为探究家猪 SOCS7基因的生理功能奠定了基础.     

State of the field: Are the results of science contingent or inevitable?

This paper presents a survey of the literature on the problem of contingency in science. The survey is structured around three challenges faced by current attempts at understanding the conflict between “contingentist” and “inevitabilist” interpretations of scientific knowledge and practice. First, the challenge of definition: it proves hard to define the positions that are at stake in a way that is both conceptually rigorous and does justice to the plethora of views on the issue. Second, the challenge of distinction: some features of the debate suggest that the contingency issue may not be sufficiently distinct from other philosophical debates to constitute a genuine, independent philosophical problem. And third, the challenge of decidability: it remains unclear whether and how the conflict could be settled on the basis of empirical evidence from the actual history of science. The paper argues that in order to make progress in the present debate, we need to distinguish more systematically between different expressions that claims about contingency and inevitability in science can take. To this end, it introduces a taxonomy of different contingency and inevitability claims. The taxonomy has the structure of an ordered quadruple. Each contingency and each inevitability claim contains an answer to the following four questions: (how) are alternatives to current science possible, what types of alternatives are we talking about, how should the alternatives be assessed, and how different are they from actual science?

Structural organization and cellular localization of tuftelin-interacting protein 11 (TFIP11)

Tuftelin-interacting protein (TFIP11) was first identified in a yeast two-hybrid screening as a protein interacting with tuftelin. The ubiquitous expression of TFIP11 suggested that it might have other functions in non-dental tissues. TFIP11 contains a G-patch, a protein domain believed to be involved in RNA binding. Using a green fluorescence protein tag, TFIP11 was found to locate in a novel subnuclear structure that we refer to as the TFIP body. An in vivo splicing assay demonstrated that TFIP11 is a novel splicing factor. TFIP11 diffuses from the TFIP body following RNase A treatment, suggesting that the retention of TFIP11 is RNA dependent. RNA polymerase II inhibitor (-amanitin and actinomycin D) treatment causes enlargement in size and decrease in number of TFIP bodies, suggesting that TFIP bodies perform a storage function rather than an active splicing function. The TFIP body may therefore represent a new subnuclear storage compartment for splicing components.Received 8 December 2004; received after revision 27 January 2005; accepted 8 March 2004The nucleotide sequence for the cDNA to mouse TFIP11 (previously known as TIP39 and TIP39kDa) has been submitted to Gen- Bank^TM/ EBI Data Bank with accession numbers AF290474 and NM_018783. The accession number for the human TFIP11 homologueis NM_012143.

本文基于正切函数提出一种新的直觉模糊正切相似度量,并将其应用在工程方案的多属性决策中。在方案决策中,通过计算理想方案与各备选方案的相似度量值,并按计算的相似度量值作出排序,选出最佳方案。也就是说,计算出的相似度量值越大,方案就越好。应用实例表明了所提直觉模糊正切相似度量决策方法的有效性与合理性。这种决策方法为工程方案的决策提供了新的途径。
